Classes of Narcotics
According to the U.S Drug Enforcement Agency (DEA), the definition for the word "narcotic" varies greatly depending on the context in which it is used. The strictest way to define the word is to include only substances that bind to opiate receptors in the brain, while the broadest definitions may include any illegal drug. The agency uses a legal definition that includes only opium, its derivatives and its synthetic substitutes as narcotics. This breakdown is an easy way to classify the drugs.
